Answer:
The statement that best describes nuclear fusion is;
Nuclei combine to form a heavier nucleus, releasing energy
Explanation:
In nuclear fusion, we have the reaction of the nuclei of two or more atoms coming together (combining) to form heavier elements and subatomic particles such as protons and neutrons accompanied by the release or absorption in energy depending on the difference between the mass of the reactants and the products
Some nuclear fusion reaction require an input of energy and such reactions are therefore not spontaneous
The best option is nuclei (two or more nuclei) combine to form a heavier nucleus, releasing energy.
Answer:
250 kgm/s
Explanation:
To calculate momentum, simply take the product of the mass and velocity.

Answer:D</h2>
Explanation:
Option A:
Surface waves are neither transverse nor longitudinal.They traverse perpendicularly or parallel to the wave's motion along the interface between different media.
Option B:
Transverse waves vibrate perpendicularly to the direction of the propagation of the wave.
Option C:
Sound is a longitudinal wave.Not a transverse wave.
Option D:
Transverse waves don't require a medium for propagation.But they propagate in medium too.
Answer:
I have sub to your channel :)
Answer:
Explanation:
We know that the work could be calculate dby:
W =
where is the component of the force in the direction of the
displacement. and d is the displacement.
So, the total work () is:
Where is the force done by the first tugboat, is the angle of the force, d is the displacement and is the force done by the second tugboat.
